The population status of grizzly bears was evaluated within broad areas known as grizzly bear zones. These zones are areas where the climate and landforms provide a common influence on grizzly bear behaviour and populations, vegetation and land use activities. There are 14 zones, 2 of which supported hisotorical populations and 12 which support current populations. The past and current impacts were assessed. Five of the grizzly bears were described and future impacts were assessed. Five of the grizzly bear zones are facing predicted large increases in impacts from human land use practices. The basis for the evaluation of grizzly bear status within grizzly bear zones was a comparison of estimated current numbers to the estimated potential of the land to support grizzly bears.
